(Maybe off-topic so i will apply self-censorship if anyone says so). I must say this is quite a paradigm shift and an interesting one. It is also something that i always rant, i mean evangelize about. It helps accelerates your own branding, which FOSS is all about - self-branding to the top of the mountain. Because in open space you cannot really sell or own anything but your content determines some Google gravity and thus yourself as originator of that content. But people get confused about been rich first not famous first - wrongly thinking that if you focus on making money you will (you won't actually if you think about it Zen-wise), and that been famous won't make you rich (you have a better chance if you are more famous than now).
Openbravo POS attracts alot of Google gravity and many are competing for it. When i first published my work, it attracts a number of inquiries and many took note of my tutorial PDF, even from the other side
My part or name also get mentioned in inquiries to Pedro SMARTJSP's contribution here. But i am perplexed why Pedro answered Mario's question with "do your homework" that sounded a bit rude (politically incorrect)
I hope its PDF comes out soon, or if it can come out first in the wiki, i can help edit it. I am famous for my writing style.
